Log message:
	gdb: btrace: fix build errors on older glibc builds
	
	It is possible to have a build of glibc where SYS_perf_event_open is not
	defined (because when the glibc was compiled, the syscall did not exist),
	but have newer kernel headers installed so that linux/perf_event.h is
	available.  In this setup, you get a build failure:
	
	./common/linux-btrace.c: In function 'kernel_supports_btrace':
	./common/linux-btrace.c:316:23: error: 'SYS_perf_event_open' undeclared (first use in this function)
	
	Update the ifdef check to also see if the syscall is available.
